Abstract

Although in this book we have focused on the statistical process control when quality characteristics are in form of attribute data, for effective analysis and quality improvement, accurate measurements can be very useful. In fact, the traditional X-bar and R-chart widely used in industry are based on variable quality characteristics. Standard techniques such as process capability analysis and variability reduction through design of experiments can be found in various texts and hence will not be discussed here. On the other hand, statistical process control techniques, especially the use of control chart for process monitoring, are usually based on the assumption that the process is stable with no significant trend.
